A two-distance touch free automatic type water supply method includes: when a sensor (132) located adjacent to the outlet (116) of a shell (110) senses an appearance of an external object at a first distance from the sensor (132), the sensing signal is an open signal, whereby water of the outlet (116) is supplied; when the sensor (132) senses a disappearance of the external object at the first distance from the sensor (132), the sensing signal is a closed signal, whereby water of the outlet (116) is not supplied; when the sensor (132) senses a first appearance and a first disappearance of the external object at a second distance from the sensor (132), the sensing signal is an open signal, whereby water of the outlet (116) is supplied; and when the sensor (132) senses a second appearance and a second disappearance of the external object at the second distance from the sensor (132), the sensing signal is a closed signal, whereby water of the outlet (116) is not supplied. |
